Smatree Battery Compatible for GoPro Hero3+ / Hero 3 Camera, Long Battery Life, 1290mAh Rechargeable, Dual Charger

I have a GoPro Hero 3 Silver (Model: CHDHN-301) with a 64GB SanDisk Ultra class 10.After fully charging all the batteries from Smatree and my original GoPro battery I set my camera to record 1080, 30FPS, wide FOV.With the Smatree battery I was able to achieve 2 hours 36 minutes and 42 seconds. (3.7v 1290mAh 4.8w)With the GoPro battery I was able to achieve 1 hour 50 minutes and 17 seconds. (3.7v 1050mAh 3.885w)I absolutely love this battery and can't wait to use it skiing!The one downside I have right now is that the battery is a very tight fit, the way they wrapped the battery with the stickers makes it double wrapped (for the handle pull out) and thus a little difficult to finagle into the camera. It DOES fit for me, I recommend pushing in the stickers a little before insertion.The battery charger gets very warm during charging (no matter which battery I use) which leads me to believe they've designed a very cheap charger for these batteries. Which isn't a problem, it's not over charging as far as I can tell but it's definitely not thermally efficient. A better way to do this would be using a direct wall to charger circuit to go from my 115v AC to the 4.2v DC instead of 115v AC to 5v DC to 4.2v DC.I hope in the future Smatree will make a more energy dense version so I can record for 4+ hours on a single charge.

Perfect. Just what I needed. I carry a PowerADD battery with me on long treks for my phone. I wanted to be able to charge my GoPro batteries also so this package did the trick. I can charge on the go on the bike or trail without worrying about a dead battery. And when I get home I can charge two GoPro cells at the same time without much hassle. Great lightweight little charging block and chord that fits in the smallest of places. Great device to have with you that makes charging on the go a breeze. One of those things you buy and your really happy you did.I have not timed the recharge on the battery, but is seems a little faster than the wall unit. The new batteries are giving me about 1 hr and 15-20 min filming at 1080p @ 60 frames. My last Smatree batteries (Non Li-Polymer) did about the same and are now down to about a hour after about a 18 months of 3-4 times a week use. The Smatree batteries out performed the original GoPro battery, which I rarely used because I never got an hour's worth or energy out of it.t it seems a little faster

It's a battery and it has done everything it was supposed to do. Lasts as long as it was supposed to.

As someone who has manufactured batteries for a living, I can tell these were made with fairly cheap materials, the housings don't seem to be much but a few layers of foil and arathane. That being said, considering the cheap price, I can see that the craftsmanship went into performance. After a full charge, these things lasted a bit over twice as long as my old official batteries for my GoPro Hero 3 (yes I'm still rocking a Hero 3 after all these years, I'm poor okay give me a break). Longevity remains to be seen, but as a few extra batteries go for recording long-form D&D sessions or hiking trips, these work great.

3rd party batteries have a reputation to not last as long as stock, and this was the case for these batteries. But, for the price, it's entirely worth it given that my stock battery has completely died. These do last about 1hr less than stock, but they do hold their charge well and haven't degraded on me so far. 10/10 would recommend!

The batteries are not living up to my expectation for life time. I purchased this to replace my aging, 4 year old, GoPro battery. My original GoPro battery was rated at 1180mAh, these are advertised as 1290mAh. When shooting video at 1080 and 60fps, my original 4 y/o battery lasts about 1hr 15mins. These batteries I get about an hour.For the money, essentially, I get replacements that are no better than the old battery. At this point I use all 3 batteries and rotate through them over the course of a day. I was hoping for something that lasted a bit longer.Note: I am pilot taking video while flying. I need to start video capture and then forget about the camera until I shut down the airplane. Inflight charging is not an option as these are used in an externally mounted camera.

I am very happy with this purchase. The packaging was good and it didn't take too long to get the batteries fully charged. It is nice and small, so you can store it in your camera bag or case. It comes with the usb cord, to charge it, but it does not come with the box that plugs into the wall, that you plug the usb cord into. I have 3, so that is no problem for me, but it's definitely worth noting. I would recommend this product to friends and family.

Does not work in a gopro 3. No instructions though it says they are included. Charger lights do random things. Don't know the status of the batteries because of this. One battery shows red the other shows green after charging. But it goes green if you unplug the charger and plug it back in. Batteries have a tab to help remove them from the camera but the tab pulls off.
